1. Introduction
Driven y recent advances in desktop computing technology, todays
network applications have increased in speed, power and the a ility to
process information. To meet the demands of these more powerful appli-
cations, two afforda le switch devices provides significant increase in
performance for your Ethernet or Fast Ethernet network. The switches
come with high num er of switched ports, each capa le of transferring
information simultaneously at full wire speed to control and allocate the
network andwidth.
Figure 1-1 Fast Ethernet Switches
The key features of this switch units are:
High Port-count and Bandwidth : Com ining large num er of 10/
100M ps- ased Fast Ethernet switched ports, the switches deliver
up to 3.2 G ps or 4.8 G ps aggregated network andwidth for your
Fast Ethernet network
Easy Migration : With 10BASE-T support on each port, the
switches provide a non-disruptive and smooth migration path from
Ethernet to Fast Ethernet network.
Easy Installation : With the functions of auto-speed-sensing and
auto-negotiation on each port, the switches support plug-and-play
installation which eliminates configuration pro lems.

2. Installing the Switch
The switch is designed to operate in workgroup environments without a
complicated configuration procedure. It also features an auto-select 100-
240V, 50/60Hz power supply unit, which works in most countries around
the world.
Before connecting the supplied power cord into the switch, check to see
that the cord voltage and current rating conform to the standards of the
country of operation.

Desktop Mounting
The switches can e placed on a desktop as a stand-alone unit. Allow
enough ventilation space etween the hu and the o jects around it.
Figure 2-3 Desktop Mounting
Rack Mounting
For mounting the switch into a 19-inch rack, a pair of mounting rackets
is included in the pack.

3. Making Network Connections
3.1 Network Switched Ports
16 switched ports and 24 switched ports are provided on these two
switch models respectively. Each port is equipped with one RJ-45 con-
nector at least. Both models provide one additional uplink RJ-45 connec-
tor on Port 16 and Port 24 respectively. Some switched ports are designed
with trunking function optionally.
Figure 3-1 Network Switched Ports

-8-
 Switched Ports
Each switched port supports one connection to a LAN segments. Each
segment is an independent shared network in one collision-domain.
The connection can e to either a 10BASE-T or 100BASE-TX device.
 MDI-X RJ-45 Connectors
MDI-X jack is la eled [X] normally to indicate the jack is designed
with internal crossover function. It allows a connection to an end
station using straight-through UTP ca le.
 Uplink MDI RJ-45 connectors
One additional MDI RJ-45 connector of each switch is provided for
easy uplink via standard straight-through UTP to other device that
supports MDI-X RJ-45 connector.
 Trunking Ports
Some switched ports can e optionally used for supporting trunking
function. This option depends on the trunking configuration setting
on rear panel. Refer to section 3.7 for more information.
3.2 Pin Assignments of MDI-X and MDI RJ-45
The following ta le shows the pin assignments of MDI-X and MDI RJ-45
connector respectively:
PIN# MDI-X Jacks MDI Jack
1 Rx+ Tx+
2 Rx- Tx-
3 Tx+ Rx+
6 Tx- Rx-
4,5,7,8 NC NC

-9-
3.3 UTP Cables
When making a connection to another device using straight-through
UTP ca le, make sure MDI-X to MDI connection rule is followed. The
following figure illustrates the pin assignments of a straight-through
UTP and a crossover UTP ca le:
Figure 3-2 Straight-through and Crossover UTP Cable
It is suggested to use straight-through UTP ca les for all UTP connec-
tions. The maximum length and UTP ca le categories used for the con-
nections to a 10BASE-T device and 100BASE-TX device are:
CONNECTEDDEVICE UTP CABLE USED & MAXIMUM LENGTH
10BASE-T device Cat. 3, 4, 5 UTP (100 meters)
100BASE-TX device Cat. 5 UTP (100 meters)

-10-
3.4 UTP Connections
The switch can support connections to the following devices:
_10BASE-T or 10/100BASE-TX network cards
_10BASE-T hu ports
_100BASE-TX hu ports
_10/100BASE-TX dual speed hu ports
_10/100BASE-TX switch ports
The following figure illustrates some connection examples:
Figure 3-3 Example of Connections to Different Devices

-11-
3.5 Operating Mode
All switched ports are designed as auto-negotiation capa le switched
ports. Each port can determine the speed and duplex type used automati-
cally through an auto-negotiation process with the remote connected
auto-negotiation capa le device. The auto-negotiation process is per-
formed upon the connection is made.
When connecting to a non-auto-negotiation device, each port also fea-
tures the capa ility to auto-sense the connection speed.
The following ta le lists the operation mode used for the switched port
when it connects to different devices. The operating mode includes the
connection speed and duplex type.
Device Connected Operation Mode Used
10BASE-T hub 10Mbps, half-duplex
100BASE-TX hub 100Mbps, half-duplex
Auto-negotiation device Auto-negotiation *2
Non-auto*1 half-duplex device auto-speed-sensing *3, half-duplex
Non-auto full-duplex device Not supported
*1 Non-auto : non-auto-negotiation
*2 determined through auto-negotiation process
*3 speed is determined by auto-sensing function
Most of 10BASE-T hu s and 100BASE-TX hu s are non-auto-negotia-
tion devices and operate on half-duplex mode.

3.6 Port-based VLAN Support
Each port of the switch unit connects to one individual LAN segment.
There can e many Ethernet nodes located on each segment. The switch
performs network data forwarding etween different LAN segments. It al-
lows Ethernet nodes located on different segments to communicate with
each other. Basically, all Ethernet nodes are in one single LAN.
For the purposes of security need or to minimize roadcasting messages,
the switches support a port- ased VLAN (Virtual LAN) function. It al-
lows you to divide the switched ports into 2 groups via a VLAN configu-
ration setting. Each port is associated with one LAN segment. As long as
the setting is made, the Ethernet nodes located in same group compose
one individual virtual LAN and the nodes located in different groups are
una le to communicate with each other.
The VLAN configuration slide switch is located on the rear panel of the
switch. Three setting positions are provided for selection.
Figure 3-4 VLAN Configuration Setting Switch

-13-
Two groups are defined when VLAN function is ena led. The setting 1
defines two groups without any overlapping. These two groups are in-
dependent and isolated. No network data can e forwarded etween two
groups. However, the setting 2 defines two groups with some overleap-
ing ports. The overlapping ports elong to two groups at the same time.
They are a le to communicate with any Ethernet nodes glo ally. De-
pending on your application need, choose the appropriate setting for
your installation.
3.7 Trunking Support
Two switch units can e cascaded together through any regular switched
port on each unit when an expansion is required. However, the transfer
andwidth etween the two cascaded ports is limited to 200M ps full
duplex.
To increase the andwidth for the connection etween two switch units,
a trunking function is implemented on the switch unit for this purpose.
Some ports can e configured optionally as trunking ports. A pair of
trunking ports composes one trunk. Two switch units can e cascaded
through one trunk (two ports and two ca les). The aggregated and-
width of one trunk can e up to 400M ps.
The port pairs which are equipped with trunking function are:
Figure 3-5 Trunking Ports

-14-
The trunking configuration setting switch is located on the rear panel
and the settings are:
Figure 3-6 Trunking Configuration Setting Switch
The following figure illustrates an example of trunk connection etween
two switches:
Figure 3- Example of One Trunk Connection

-15-
Note :
1. A pair of crossover UTP ca les should e used at the same time for
one trunk connection. The length of each ca le can e up to 100
meters.
2. When the switched ports are ena led as trunking ports, they can
only serve trunking function, ut no other function.
3. The 16-port switch and 24-port switch can trunk to each other.
4. Since the trunking is proprietary, the switches do not support trunk
connection to other rands switches.
The following figure illustrates another example of trunk connections
etween three switches:
Figure 3-8 Example of Two-Trunk Connections

4. LED Indicators
4.1 LED Panels
The switch provides comprehensive LED indicators for diagnosing and
monitoring the operation of the unit as illustrated elow:
